CAN-CLOSURE.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed March 6, 1906. Serial No. 804,557-

.l'o all whom it may concern:

Be it known that I, GEORGE H. DUNBAR, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Imrovexnents in Can-Closures, of which the folowin'g is a specification.

This invention relates to cans, and particularly to means for closing the latter, and has for its object to provide a novel and simple top for a can provided with an iinperforate removablydepressed element which is integrally formed with the can-top and at the timethat the latter is shaped and constructed and which must be removed by cutting when it is desired to gain access to the contents of the can and has an auxiliary cover to'coop- :erate therewith to preserve and avoid deterioration by a continuous exposure to the air of the contents of the can after the top is opened.

To the ends stated the invention consists in the construction and arrangement of arts, which will be more fully hereinafter set orth'.

In the drawings, Figure 1 is a sectional elevation of the head portion of a can, showing the improved top applied thereto and the auxiliary cover arranged above the same.

.Fig. 2 is a similar view showing theimperforate depressed part having the opening formed therein by cutting the same and the auxiliary cover applied thereto. Fig. 3 is a view similar to F-ig. 2, showin the auxiliary cover in position for remova from the depressed part of the top. Fig. 4 is a top plan view of the can as it appears before t 1e ,depressed part thereof is out and without the auxiliary cover. Fig. 5 is a view similar to Fi 4, showing the auxiliary cover applied.

imilar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates the can-body, which is of ordinary or usual construction and rovided with a top 2, the upper edge of the ody being primarily constructed with an outwardlyrejecting surrounding flange 3 and the top aving a corresponding flange 4, the flanges 3 and 4 being secured by crimping or seaming the same to the body of the can without the use of solder or acid The top 2 is formed with a depression or dish shaped cavity 5, which is stamped therein at the time that the said to i is struck or cut out of tin-plate. The dish-s aped cavity is thus constructed integral with the top, and the bottom thereof is impe'rforate, and when it is desired it will also have impressed therein by suitable dies the words Cut this out. After the top is applied to the can and secured the contents of the can are only accessible by removing the bottom of the de-- pression or dish-shaped cavity .5. When the bottom of the depression or dish-shaped cavity 5 is removed by cutting out the same, the contents of the can may be reserved against deteriorating influences o the surrounding atmos here through the medium of a dish-shaped auxiliary cover 6, which is frictionally held in the depression and has a flange 7 surrounding the same. The flange 7 projects over the portion of the top adjacent to the depression or dish-shaped cavit 5 and is removable b introducing a suitab e implement between t e flange 7 and the cantop and exerting a rying operation on the said implement. T e bottom of the auxiliary cover 6 will also have im ressed or stamped therein the words Pry t is u From the foregoing it will be observe that the can constructed in accordance with the features of this invention is made without any opening or filling mouth, the can-body having its contents placed therein rior to the application of the top, and after the said top is secured, as hereinbcfore set forth, the can will be hermetically sealed without the use of solder or acid, and by this means a sanitary can will be provided.

.It will also be understood that the can may be made in various dimensions and that the position of the depression or dish-shaped cavity 5 may be modified without departing from the features of the invention.

Having thus described the invention, what is claimed is 1. The combination with a can-body, of a one-piece top connected to the u per edge of the can by a hermetic joint, sai top having an integral depression with an imperforate 100 bottom adapted to be out out, and a removj cut out and a removable mp frictionelly m able cap for such depression, said ca. having fitted W1 thin the depression. a downwardly extendi wall w 'ch fits In testimony whereof I have hereunto set snugly in the side walls 0 said depression in my hand in presence of two subscribing witthe'to nesses.
